Battle of Rancagua

The Battle of Rancagua was the decisive battle of the Chilean Civil War, in which a Spanish Royalist army under Mariano Osorio crushed a Chilean army under the command of patriot general Bernardo O'Higgins. The Chileans inflicted heavy losses on the Spanish first day, but on the second day, O'Higgins ordered his men to flee and disperse, having a premonition that he would not win. He fled to Argentina with the remnants of his army, and the Spanish imposed brutal rule on Chile.
